Miele W 3748 Operating Instructions

							Disconnect the machine from the
mains electricity supply and
withdraw the plug from the socket
before cleaning the machine.
The washing machine must not
be hosed down.
A range of Miele branded cleaning and
conditioning agents are available to
order from your Miele dealer, the Miele
Spare Parts Department, or via the
internet on www.miele-shop.com
External casing and fascia
panel
Clean the casing using a Miele E-Cloth,
or with a mild non-abrasive cleaning
agent or soap and water using a well
wrung-out cloth. Wipe dry with a soft
cloth.
The drum and any stainless steel
outer panels can be cleaned using a
suitable proprietary stainless-steel
cleaning agent following the
manufacturers instructions on the
packaging.
Do not use solvents, abrasive
cleaners, glass cleaners or
all-purpose cleaning agents.
These might damage plastic
surfaces and other components
because of the chemicals they
contain.Extra cleaning
Carry out a hot wash (70°C or above)
with powder detergent approx. every 6
weeks to help prevent deposits building
up in the machine. These can occur
when washing is mainly done at low
temperatures, and also lead to
unpleasant smells. If you have no
reason to wash occasionally at this high
temperature, then run a Cottons 95°C
programme with detergent but no
laundry at regular intervals.
Cleaning the detergent
dispenser drawer
Remove detergent residues regularly.

Pull out the detergent dispenser
drawer until a resistance is felt. Press
down the release catch and at the
same time pull the drawer right out of
the machine.

Clean the detergent drawer with
warm water.

							Clean the siphon.
1. Remove the siphon from
compartmentand rinse under
warm running water. Clean the
siphon tube in the same way.
2. Replace the siphon.
If starching frequently, thoroughly
clean the siphon and siphon tube
regularly. A build-up of starch will
cause them to get clogged.Cleaning the detergent dispenser
drawer housing
Use a bottle brush to remove
detergent residues and limescale
from the jets inside the detergent
dispenser drawer housing.Descaling the machine
If the correct amount of detergent is
dispensed, the machine should not
need to be descaled. If, however, you
do wish to descale the machine only
use proprietary non-corrosive descaling
agents and strictly observe the
instructions on the packaging.
Cleaning and care

							Cleaning the water inlet filters
The washing machine has two filters to
protect the inlet valves.
These filters should be checked every
six months or so, or more often if there
are frequent interruptions to the water
supply.
To clean the filter in the union in the
open end of the inlet hose:
First turn off the stopcock.
Unscrew the threaded union
connecting the free end of the inlet
hose to the stopcock.

Remove the rubber seal1from the
recess.

Using pointed pliers, take hold of the
plastic filter bar2, remove the filter
and clean it.

Put the filter and seal back in the
reverse order and reconnect the
hose.

Turn on the stopcock and check the
connection is watertight. If it leaks,
tighten the connection.To clean the filter in the water inlet
valve:
Using pliers, carefully loosen the
ribbed plastic nut on the inlet valve
and unscrew.
Use pointed nose pliers to withdraw
the plastic filter by the bar (see
illustration). Clean, put back and
secure.
The two filtersmustbe put back in
place after cleaning.

The laundry has not been
spun properly and is still
wet.The machine detected an
imbalance during the final
spin and reduced the
spin speed automatically.Include both large and
small items in the load as
this will give better
distribution.
The laundry has not spun
satisfactorily.The spin speed selected
was too low.Select a higher spin
speed next time.
The pump makes strange
noises.This is not a fault! These noises occur at the end of a
pump sequence as a normal part of the operation.
There is a lot of
detergent residue in the
detergent drawer.The water pressure is too
low.– Clean the water inlet
filter.
– Select Water plus.

							An unsatisfactory wash result
Problem Possible cause Remedy
Liquid detergent
does not give the
required result.Liquid detergents
usually contain no
bleaching agents.
They do not remove
fruit, coffee and tea
stains.–Use a general purpose
detergent containing a
bleaching agent.
–Pour stain removers into
compartmentof the
dispenser drawer and liquid
detergent into a dispenser ball.
–Never put stain removers and
liquid detergent together in the
dispenser drawer.
Grey, greasy
particles cling to
washed laundry.Insufficient amounts of
detergent were used
to break down the
particles of grease in
heavily soiled laundry.– Use more detergent.
– Before washing the next load
run aCottons 95°Cprogramme
with powder detergent but
without a load.
A stale smell is in
the drum and on
laundry.Low temperature
washing.– Before washing the next load
run aCottons 95°Cprogramme
with powder detergent but
without a load.
White residues
which look like
powder detergent
are seen on dark
textiles after
washing.The detergent
contained compounds
(zeolites) to aid water
softening which are
not soluble in water.
They have ended up
on the laundry.–
Try and brush off the residues
with a soft brush once the
laundry is dry.
–
Wash dark textiles using a
detergent which contains no
zeolites. Liquid detergents
usually contain no zeolites.
–
Use theDark garments
programme.
Clothes are coming
out creased.Programme was
overloaded.–
Reduce quantity of clothes in
drum.
The wrong
programme was used.–
Check care labels and the
programme chart.
–
Use easy iron conditioners.

Switch the washing machine off.
There is a lever behind the detergent
drawer fascia panel.
Remove the lever.

Use it to open the access flap.Blocked drain outlet
If the drain outlet is blocked, up to
25 litres of water will be retained in the
machine.
Caution: if laundry has been
washed at a high temperature, water
draining out of the machine will still
be hot. Danger of scalding!
Procedure for draining the machine

access flap.
When draining water from the
machine, donotunscrew the drain
filter completely or take it right out.

							Once the flow of water ceases:
Remove the drain filter completely.
Clean it thoroughly.

Remove any foreign objects (e.g.
buttons, coins, etc.) and fluff from the
filter housing. Turn the impeller by
hand to check that it rotates freely.
Any foreign object causing an
obstruction should be removed.

Put the drain filter back in place and
secure.
Make sure the drain filter is
securely tightened. Otherwise there
is a risk of water leakage during use.
Opening the drum door

is stationary before reaching into the
machine to remove laundry.
Reaching into a moving drum is
extremely dangerous.
